Weir and lock drives move slowly but against heavy loads and with a long return line. The 4WRTE10W6-100L-4X/6EG24EK31/A1M therefore returns pilot oil externally, draws it internally and controls 100 l/min nominal flow with symbol W6 from a ±10 V command.

Total price
A long, throttled return line puts back pressure on the pilot stage of a valve. The 4WRTE10W6-100L-4X/6EG24EK31/A1M avoids that with external pilot oil return and internal supply, while providing 100 l/min nominal flow through spool symbol W6.
Benefits
- Symbol W6 at 100 l/min nominal flow, throughput up to 170 l/min.
- Command value ±10 V taken straight at the valve, 24 V DC supply.
- Spool travel measurement keeps the spool tracking the command.
- Internal pilot oil supply, external pilot oil return per the type code.
- 350 bar operating pressure, NBR seals, hydraulic fluid HL.
- 9.58 kg on connection diagram ISO 4401-05-05-0-05, size 10.
